IF RELAY HAS NOT BEEN UPDATED MOST LIKELY IT IS THE DEFAULT
The relay is under the battery and you remove the old and when the new revised
or re-engineered relay new holes have to be drilled. cost 75 dollors doing it your self.
found out some dealers try to charge 125? the below is good to start off with for routine stuff to check off the list.
now with the 2003 jeeps you need to check the 40amp under hood fuse first off. Fuse box located behind battery on side of fender . you should then check the fan motor. You can use jump leads and connect to pin with blue wire and the other pin being grnd/ blk wire and use a twelve volt source If fan works fine then relay is most likely culprit . when engine warms up to I think 95 degrees fan should kick on. disregard the rest of this info .
Revised. MOST LIKELY THE RELAY IS DEFAULT AND NOT TURNING THE FAN ON
AT THE PROPER TEMP AND WILL CAUSE THE ENGINE TO OVER HEAT
On a Jeep Liberty Limited 2003, the 40 amp fuse is in the fuse box under the hood and right by the battery. The fan relay is located about half way back on the drivers side, and is LOCATED UNDER THE BATTERY, AND NOT VISABLE. THE NEW RELAY HAS BEEN REVISED OR RE-ENGINENEERED AND NEW HOLE WILL HAVE TO BE DRILLED NOT A HARD JOB MAYBE 20 MINS OR SO. The relay has been modified in recent years and has cooling pins added. Modifications to the screw/hole placements will need to be made.
